Chicago Building Permits
Official daily public dataset and SODA API of Chicago building permits issued from 2006 onward, including documented permit type and current status fields.
Questions this answers
3 · best fit firstThe standing Chicago address/parcel permit API supplies permit identity, type, current status, issue date, work type and work description. Caller-selected records explicitly identify sprinklered or non-sprinklered construction and sprinkler work when stated by the permit, providing jurisdiction-issued chronology only, not proof of present installation or operability.
Chicago's daily public permits API provides address/permit records issued from 2006 onward with permit type and current status, allowing roof-related records to be selected when the record text/type identifies roofing. The cited metadata does not establish a dedicated roof-work classification or document issue, completion, index-through, and query dates on every matched record, so those pins must be retained as gaps.
The public Chicago address/permit dataset and API provide issued permit type and current status as local supplemental evidence.
